<P>PROBLEM TO BE SOLVED: To make power on/off changes on plug receptacles at plural places of operation controllable or visible through a network, and also facilitate utilization of new functions at each place of operation. <P>SOLUTION: A plurality of host controllers 2 are connected to a centralized control apparatus 4 via a network 3, where the host controllers 2 each acquire the amount of power used and the power on/off state in units of plug sockets received from a plug receptacle 1 subordinate thereto and then transmit acquired information to the centralized control apparatus 4, the transmitted information being stored in a data storage unit 5 using respective identification information. The centralized control apparatus 4 has a control scenario fed into it beforehand, so that a scenario processing unit 6 can monitor the sufficiency of control conditions indicated in the control scenario from the information stored in the data storage unit 5, determine the content of control in plug socket units, and instruct the host controllers 2 to change power on/off of a specific plug socket. <P>COPYRIGHT: (C)2013,JPO&INPIT |
